The small 20cl bottle is intensely flavoured with botanicals which means just 5ml of Hayman’s Small Gin is required to make a balanced G&T, which in theory reduces alcohol consumption by 80%.

Fifth generation family member, Miranda Hayman, said: "Many consumers are actively looking to reduce their alcohol consumption but are keen to continue enjoying that classic gin flavour they have grown to love. Small Gin is the perfect solution – a real gin that allows you to mix a true G&T with just a fraction of the alcohol."

Small Gin contains just 15 calories per 5ml and is available to pre-order at haymansgin.com for delivery in August at £26 per 20cl bottle.

Distiller Sam Pembridge added: "We based the flavour profile for Small Gin on a classic London dry and getting all that wonderful botanical character into such a small serving size was an incredible challenge. 

“We are working at the outer limits of what can be achieved but the flavour profile is spot on. In blind tastings completed at our distillery, even the most experienced of gin drinkers were unable to tell the difference between a Small Gin & Tonic and a London dry Gin & Tonic.”
